(57) In this method for producing a Portland cement clinker, the proportion of silico-manganese slag used in a starting-material mixture is set so as to be 2-10 mass%. As a result, a Portland cement clinker is achieved which exhibits excellent sinterability, and which can be used to obtain cement. Accordingly, provided is a method for producing a Portland cement clinker with which excellent sinterability and strength development properties are achieved without adversely affecting the physical properties thereof.
